DRAFT-EVENER.

Specification of Letters Patent.

Patented May 1, 1906.

Application filed October 24,1905. Serial No. 284,177-

To all whom it may concern.-

Be it known that we, HINRY THIEDEMANN' and J URGEN HENRIGH THIEDEMANN,citizens of the United States, residing at Hickman, in the county ofLancaster and State of N ebraska, have invented new and useful Improvements in Draft-Eveners, of which the following is a specification.

Our invention is a draft-evener, and has for its object simplicity ofconstruction and efficiency of operation and to this end it consists incertain novel features of construction hereinafter described andclaimed.

In the accompanying drawings, Figure 1 is a plan view of the invention.Fig. 2 is an edge view thereof. Fig. 3 is a plan view showing theposition of the parts when turning a corner.

Referring specifically to the drawings, 10 denotes a plow-beam, and 11the clevis thereof to which the evener is attached. The supporting-frameof the evener comprises spaced top and bottom plates 12 and 13,respectively, which are fastened together by bolts 14, 15, and 16. Thebolts 14 and 15 are near the ends of the frame, and the bolt 16 islocated between said ends. The frame is connected to the plow-clevis bybars 17 and 18, respectively. The bar 17 extends to and is made fast tothe end bolt 14. The bar 18 is formed with two arms or branches 19 and20, respectively. The arm 19 extends to and is made fast to the end bolt15, and the arm 20 extends to and is made fast to the intermediate bolt16.

At 21 is indicated an evener-bar which is ivoted on the bolt 16 betweenthe top and fiottom plates of the supporting frame. Each end of theevener-bar is shaped so that arc shaped slots 22 and 23, respectively,are formed, which slots are for a purpose to be described hereinafter.

An evener-lever 24, carrying a doubletree 25, extends between thesupporting-frame and is pivoted to the end bolt 14. On this same bolt anangle-lever 26 is pivoted, said lever having at one end arearwardly-extending arm 27, which is connected by a link 28 to theevener-lever 24. Preferably the lever 26 and link 28 are in pairs, asshown. The end of the angle-lever 26 opposite the arm 27 carries a bolt29, which extends through and works in the slot 22.

A second evener-lever 30, carrying a denbletree 31, is pivoted on theend bolt 15. The short arm of this lever extends between thesupportinq-frame and carries a bolt 32, which extends t irough and worksin the slot 23. The lever 30 has a number of holes 33, in which theattaching means of the doubletree 6o 31 are secured, so that theleverage can be adjusted.

The evener can be reversed and worked 011 either the right or left side,and by the use of a trebletrce it can also be used as a five-horseevener. The teams are held to a straight pull, there being no sidedraft, and the draft is evenly distributed. Upon turning a corner theparts by reason of the engagement of the bolts 2.) and 32 in the slots22 and 23 of the evener-bar assume the position shown in Fig. 3, so thatthe teams are pulling at almost a right angle to the plow, whichfacilitates making the turn. After the turn is made all parts readilyassume their normal position, 7 5 the slots 22 and 23 being so shapedthat no binding of the parts will take place. The evener will alsoreadily operate upon making a turn to the right. To further enable theparts to move freely without binding, the bolts 29 and 32 can be fittedwith friction- .rollers. The evener can also be applied to a harvesterand when so applied will effectively take up all side draft.

Having thus described our invention, what is claimed as new, and desiredto be secured by Letters Patent, is

1. A draft-evener comprising a supporting frame, an evenerbar pivoted insaid frame and formed with arc-shaped slots in its ends, a pair ofevener-levers pivoted on opposite sides of the evener-bar andoperatively connected, respectively, at their inner ends to the slots inthe evener-bar.

2. A draft-evener comprising a supporting frame, an evener bar pivotedin said frame and formed with arc-shaped slots, a pair of evener-leverspivoted in said frame and carrying at their inner ends bolts which work,respectively, in the slots of the evener- I00 bar.

3. A draft-evener comprising a supporting frame, an evener bar pivotedin said frame and formed with arc-shaped slots in its ends, anevener-lever and an angle-lever pivi oted in said frame on a commonpivot, said angle-lever being connected at one end to the names to thisspecification in the presence of evener-lever, and its other end beingopera- 5 two subscribing Witnesses.
